time machine.... imposseble to create...

Have you read theories involving time travel? Logically it doesn't sound possible. However on paper it seems quite possible. Albert Einstein had a theory and many others thought it was not possible. But time told the truth. The same man, A. Einstein, also believed it was possible and would have provided a detailed theory if he had lived long enough. But it still doesn't seem possible UNLESS the future is already written. Doesn't that sound more logical? If the future is already set in stone then it would be possible to fast forward it like a dvd. It seems like there are too many variables to be able to travel to the future. But it would be more likely to go into the past because it has already happened.
